Difference Between ALU and CPU

Main Difference

A computer is complete when many components come together to form a device, each of which has its own meaning and the way they make things happen. The two most important parts covered in this article are CPU and ALU, they are known as Central Processing Unit and Arithmetic Logic Unit. The former is responsible for all the activities that are performed on a device and is then called the heart of the computer. While the other is in charge of the logical and mathematical operations that occur within the system and makes sure that certain instructions are completed in the correct way.

Definition of ALU

ALU, which is more widely known as Arithmetic Logic Unit, is the main component of the central processing unit. The main job of this unit is to perform all logical arithmetic operations such as addition, subtraction, multiplication, division and many others. It is considered the most dominant part of the CPU, and many of the original features will start working without it. In most modern computers, it is divided into two more parts; the first is the AU, which deals with arithmetic operations such as those mentioned above and the second is the LU, known as a logical unit that deals with the logical operations that define the subject. Many computers have more than one of these units and handle fixed-point and floating-point operations at the same time. In computers used in homes, most of the time this process has an appropriate chip called a numerical coprocessor. The data that comes your way is direct, as are the implemented instructions. The input is usually the instruction word which contains a mode of operation, more than one operand, and sometimes a format code is also present. The output, in this case, consists of a result that is placed in a storage log and has specific settings indicating that the action was successful. A separate storage space is present within the system and has several other features, such as giving negative values, performing operations on numbers that are not supported by logic, and many others. The input is usually the instruction word which contains a mode of operation, more than one operand, and sometimes a format code is also present. The output, in this case, consists of a result that is placed in a storage log and has specific settings indicating that the action was successful. A separate storage space is present within the system and has several other features, such as giving negative values, performing operations on numbers that are not supported by logic, and many others. The input is usually the instruction word which contains a mode of operation, more than one operand, and sometimes a format code is also present. The output, in this case, it consists of a result that is placed in a storage log and has specific settings indicating that the action was successful. A separate storage space is present within the system and has several other features, such as giving negative values, performing operations on numbers that are not supported by logic, and many others.

CPU Definition

The CPU is the most important part of the computer and is known by many names such as processor, microprocessor, central processor, and others. It is the logic circuit that acts on the various activities that occur within the device and is called the heart of the computer. The steps involved are the same as the process mentioned above where the instruction that is fetched from the memory unit, then decoded to be understandable by the computer, reading the instruction and then executing it becomes the next part. The essential elements that become part of the processor are the arithmetic logic unit that performs all arithmetic and logic operations, a floating point unit known as the math coprocessor. The next part is called the registry which contains all the instructions and other data and supplies it to the system when needed. The last two parts are the L1 and L2 cache where its inclusion in the CPU saves time, and the data does not have to be entered over and over again. Most systems in the world today have more than two processors to improve performance. This action helps in a way that when the computer has to work at faster speeds, even though these are two separate processors, combining them into a single socket causes them to then run at sub-second speeds. In the case of a personal computer, this term is used for a processing element contained within a single integrated circuit called an IC chip. The major providers of these processors are known as Intel and AMD. Most systems in the world today have more than two processors to improve performance. This action helps in a way that when the computer has to work at faster speeds, even though these are two separate processors, combining them into a single socket causes them to then run at sub-second speeds. In the case of a personal computer, this term is used for a processing element contained within a single integrated circuit called an IC chip. The major providers of these processors are known as Intel and AMD. Most systems in the world today have more than two processors to improve performance. This action helps in a way that when the computer has to work at faster speeds, even though these are two separate processors, combining them into a single socket causes them to then run at sub-second speeds. In the case of a personal computer, this term is used for a processing element contained within a single integrated circuit called an IC chip. The major providers of these processors are known as Intel and AMD. this term is used for a processing element contained within the single integrated circuit called an IC chip. The major providers of these processors are known as Intel and AMD. this term is used for a processing element contained within the single integrated circuit called an IC chip.

Differences in a nutshell

  1. The full name of ALU is Arithmetic Logic Unit and the full name of CPU is Central Processing Unit.
  2. The main task of the ALU is to perform all the operations that are related to human logic and mathematics, while the main function of the central processing unit is to make sure that all the functions are performed accurately on time.
  3. An arithmetic logic unit is part of the central processing unit.
  4. There may be one or more central processing units in a computer depending on the requirement, but there is only one
  5. Arithmetic logic unit in a central processing unit.
  6. A CPU was also known as a processor, it interprets and executes the basic instructions that operate a computer. An ALU performs basic calculations such as addition, subtraction, multiplication, and division.
  7. The core parts of the ALU include an arithmetic unit and a logic unit, while the main parts of the CPU include the arithmetic logic unit, the floating point unit, the register that contains all the instructions, and the L1 and L2 cache.

Final Thought

We hear a lot about these terms in our daily routines and therefore this article clarifies all the main functions, their working and examples to make sure that everything is simplified for the reader to come to know more about a central processing unit and arithmetic. . logical drive.
